Not to sound like a greenhorn but just what caliber is a .40 2 1/10 ? Is it a sharps bottle neck or straight or as the caliber and length would hint to is it a .40-65 WCF. Iv'e seen a couple of shiloh's in that caliber that are in my price range but can't find out exactly what it is and it appears the seller only knows whats marked on the rifle.
